Cannot install from menu, is there a way to force install?

I just upgraded to Krypton, I probably shouldn’t have done that as I had the previous version running perfectly and Aeon Nox all setup and looking great.

The new skin doesn’t look good on my front projection theater setup. I went into the menu to try and download Aeon Nox, when I click add skin the menu box simply disappears, it never loads a list of skins for me to choose from.

Is there a way to download Aeon Nox manually and install it myself?
